Problems solved by technology

However, mining areas with extremely complex hydrogeological conditions are often threatened by multi-layer water damage, not only by the huge thick Ordovician limestone aquifer in the coal measure base, but also by the thin coal measure limestone aquifer. How to efficiently and economically control water damage and provide technical support for mining safety is also a technical problem of water control in coal mines that needs to be solved

Abstract

The invention discloses a double-layer water disaster treatment method based on regional treatment, which comprises the following steps: step A), analyzing hydrogeological conditions of a treatment region: starting from analyzing parameters of a water-bearing layer of the treatment region, on the premise that an exploited coal seam is threatened by a coal series thin limestone water-bearing layer and a hidden vertical water guide channel hydrogeological condition exists, analyzing the parameters of the water-bearing layer of the treatment region; analyzing the condition of the hydrogeological condition of the governance area; and step B), a treatment scheme arrangement technical method based on a ground area treatment technology: corresponding hole arrangement modes are set according to hydrogeological conditions of different conditions, and threats of an Ordovician limestone aquifer and a coal series thin limestone aquifer to mining are thoroughly relieved. The technical problem of short-distance double-layer water disaster treatment faced by a mine with complex hydrogeological conditions is creatively solved by adopting the drill hole arrangement technical method.

Description

technical field [0001] The invention relates to the technical field of water hazard treatment in coal mines, in particular to a two-layer water hazard treatment method based on regional treatment. Background technique [0002] The exploration and treatment technology of coal mine water hazard surface area has effectively solved the technical problem of water hazard prevention and control in the confined aquifers of coal mines. The mine has been mined safely, and good economic and social benefits have been achieved. The technology has been widely promoted in large water mining areas across the country. However, mining areas with extremely complex hydrogeological conditions are often threatened by multi-layered water hazards, not only by the huge thick Ordovician limestone aquifer in the coal measure base, but also by the thin coal measure limestone aquifer. How to manage water hazards efficiently and economically to provide technical support for mining safety is also a tech...
